DEVICE FOR ILLUM INATING BAS'MENTS AND DARK ROOMS.

SPECIFICATION formingpart of Letters Patent N o. 583,580, dated June 1, 1897'.

Application filed March 26, 189 7.

To (ZZ whom it may cmwrn:

,Be it known that I, JAMES G. PENX YCL'ICK, a-subjeet of the Queen of Great Britain, rcsiding at Toronto, in the county of York,

5 Province of Ontario, and Doninion of Canada, have inventcd certain' new and useful Improvements in Devices for Illnminating lasenents and Dark Rooms, of which the following is a specification.

My invention relates to improvements'in devices for lighting base'nents and dark rooms. l `igure 1 is a View of .a basement with a hinged or movable prism-plate and prisnitiles. Fig. 2 is a View of a basement with a fixed prism plate and prism-tiles. Fig. 3 is a View of a basement and subbasement with prisni-files. and prism-plates, the basement prisnilato being pivoted to Swing with the door. Fig. &is a View of a basement with prisn-tiles Varying in angnlar arraugencnt systematically.

The drawings are ntended to give an illustration of the use of the invention with some of its modifications. 2 5 Like parts are indieated by the same letters in all the figures.

- A is the basenent; 13, the snbbasement; O, the vault, 1), the prism-plate in the subbasement; E, the prisn-plate of the basement; F, the prism-tiles associated with theprisn-plate E; G, the prism-tiles associated with the prism-plate I). The p'risn-platcs are composed of prisn-lights (this being the tradenamc) of the general nature of the prisnilights shown in my Patent No. *319,990, and by this means whatever light falls upon them is directed, as indicated in dotted lines, so as to be carried toward the rear and diltused throughout .the basenent or snbbasement. 40 The prisni-lights and prisn-plates obviously 'maybe faced so as to actas either refraetors or refleet0rs--in other words, may be turned with either side inward. The prism-tiles must be located to receive the light and of 4 5 such character as to throw the light onto these prism-plates, and I thereforc, in the case of basement and subbasement structures, prefer to divide the prism-tiles into two sections. One section lar-range with angles suitable to direct the light, prefcrably by reflection, upon the prism-plate E, and the other section I ar- Seral No. 629,290. Ne model&

range with auglcs less sharply iclined and adapted to throw the light onio the prismplate D. The prisn-tiles F and G are intended, preferably, to be substantially the prism-tiles or vault-lighis of my Patent Ne. 568,'780. The angular arrangeinent of the faces of the prisms on the prism-tiles and ol' 'the faces of the prisms on the prism-plaies or prism-lighis and the iuclination of the prismtiles and the inelination of the prisni-1 dates may, of course, obviously be varied to suit the circumstances and the neecssities ol` each case. The prisnilato l'is shown in one ease as hinged at ll to swing outwardly at the bottom, and in Fig. i) tleprism-plaie is shown as supported so 'as to swing like a door, and elsewhere in the figures the prism-plates are shown as fixed. In other words, such prisniplate's may be movable or fixed, so'asto aecommodate the' various conditions as they arise.

The results sought to be accomplished by this invention can be attained by the use of my said prism-tiles in a pavement and my said prism-lights in the prism-plates or lucidux, as I have called the prism-platc which separates the vault from the basemcnt, or separates the room, into which the light is first received, from that into which it is in- So tended to be led, or which iniervenes between the prisni-files and theroom to be lighted seas to be traversed by the light, and which leads thelight from the deviee onto which it is first received orfron the roon into which it is first received to the apartment where it is intended to be utilized.

The ideal form of the device is obviously that which distributcs the light transmittcd by the prism-tiles uniformly over the receivs go in g-surface of the prisn-plate,whenec it is discharged or led in substantiallyparallel lines back through the prism-plate and into the basen'ent or room to be lightcd; but for all ordinary purposes such results can be sub- 9 stantially accomplished, as previously stated, by the use of my patented prism-tiles and prism-plates, and henee they su fieiently illustrate the general idea..

llowever, in Fig. %h I have shown a diil'er- Ioo ent form of prisni-tile for thepavenent. In this ease the prisn tile or tiles have their angles Varying systenmtieally from the buili'l- 'ingt-oward the street, and of course this Variation may be either by iner sing the zngles inwardly 01' ontwardly, the object being to prodnee unfornity of light on the' prisniplate, and this mit-y be (lone, et' course, by threwing the light its inrlieated in the figures, or by throwing the light froni the prisn-tiies near the buildingonto thebotton of the prisnipinte and the light front near the Street onto the top of the prisni-pime.. In the ordinary eonstruetion ot' buildings there is an enter Vnnlt under the pmenent, and there is ft eonsiderztble (lOWHWH'tl projeetion ol' the' supporting-l'rnnework ol' the building :t the front'. ot' the paYenent. The pm'enient is in many instanees froni one to two feet higher than the bottom etthe girder whieh 'forms the top of the basemeni -openings, and my in- Ventien presents :t praetietl means forgetting the light around this girden se to speak,

and otlemling' it froni the Tanit inte the ilarle bnseinent. i
